IMPORTANT SAFETY
INSTRUCTIONS
When installing and using this electrical equipment, basic safety precautions should be
observed including the following:
READ AND FOLLOW ALL
INSTRUCTIONS
1. WARNING - To reduce the risk of injury, do not permit children to use this
product unless they are closely supervised at all times.
2. DANGER - RISK OF CHILD DROWNING. Extreme caution
must be exercised to prevent unauthorized access by children. To avoid accidents,
ensure that children cannot use this spa unless they are supervised at all times.
*NOTE: A wire connector is provided on this unit to connect of a minimum No. 6 AWG
solid copper conductor between this unit and any metal equipment, metal enclosures of
electrical equipment, metal water pipe, or conduit within 5 feet (1.5m) of the unit.
3. DANGER - RISK OF ELECTRIC SHOCK. Install spa at least
five (5) feet (1.5M) from all metal surfaces. A spa may be installed within five (5) feet
(1.5M) of metal surfaces if, in accordance with the National Electrical Code, each
metal surface is permanently connected by a minimum No. 6 AWG (8.4mm) solid
copper conductor attached to the wire connector on the terminal box. A grounding
lug is provided for this purpose.
4. DANGER - RISK OF INJURY. The suction fittings in this spa are
sized to match the specific water flow created by the pump. Should the need arise to
replace the suction fittings or the pump, be sure that the flow rates are compatible.
*NOTE: Never operate the spa if the suction fittings are broken or missing. Never replace
a suction fitting with one rated less than the flow rate marked on the original suction fitting.
5. DANGER - To reduce the risk of injury to persons, do not remove the suction
grate. Suction through drains and skimmers is powerful when the jets in the spa are
in use. Damaged covers can be hazardous to small children and adults with long hair.
Should any part of the body be drawn into these fittings, turn off the spa immediate-
ly. As a precaution, long hair should not be allowed to float in the spa.

INSTRUCTIONS (CONT.)
6. WARNING. Install the spa so that water can be easily drained out of the
compartment containing electrical components so as not to damage equipment.
When installing the spa make sure to allow for an adequate drainage system to deal
with any overflow water. Please allow for at least 2 feet of clearance around the
perimeter of the spa to provide enough room to access for servicing. Contact your
local dealer for their specific requirements.
7. WARNING - TO REDUCE THE RISK OF INJURY:
(A) Reminder - Never allow anyone to dive into a spa. Always enter feet first.
(B) Always enter and exit a spa slowly.
(C) Do not use the spa alone.
(D) Before entering the spa, always measure the water temperature with an accurate
thermometer. Tolerance of water temperature regulating devices can vary as much
as plus/minus 5° F (3° C).
(E) Persons suffering from obesity or with a medical history of heart disease,
diabetes, high or low blood pressure or circulatory system problems should
consult a physician before using the spa.
(F) Since excessive water temperatures have a high potential for causing fetal damage
during early months of pregnancy, pregnant or possibly pregnant women should
limit spa water temperatures to 100° F (38° C).
(G) Excessive water temperature can be dangerous. The water in the spa should
never exceed 104° F (40° C). Water temperatures between 100°F (38˚C) and
104°F (40˚C) are considered safe for a healthy adult. Lower water temperatures
are recommended for extended use (exceeding 10 minutes) and for young
children. Long exposures at higher temperatures can result in hyperthermia.
(H) The use of alcohol, drugs, or medication before or during spa use may lead to
unconsciousness with the possibility of drowning.
(I) Persons using medication should consult a physician before using a spa since some
medication may induce drowsiness while other medication may affect heart rate,
blood pressure and circulation.
(J) The spa should be covered with an approved locking cover when not in use,
to prevent unauthorized entry injuries.

(I) Children’s body temperature can increase more rapidly than adults in the same
water with elevated temperatures (above 99° F). Children should spend less time
in water above body temperature than adults.
8. WARNING - The use of alcohol, drugs, or medication can greatly increase the
risk of hyperthermia.
(J) The use of alcohol, drugs, or medication before or during spa use may lead to
unconsciousness with the possibility of drowning.
